Former Secretary of State John Kerry revealed to Fox News host Dana Perino the Obama administration had known Syrian dictator, Bashar al-Assad, had kept some of his chemical weapons, despite agreeing to hand over the country’s entire stockpile.

Kerry stated in 2014 that they had gotten rid of all the “declared” chemical weapons after the United States and Russia struck a deal the year prior to remove tor destroy Syria’s arsenal in exchange for indefinitely stalling the prospect of U.S. air strikes.

“We said we got a hundred percent of the declared weapons out, which is what the Organization for the Prevention of Chemical Weapons was able to track,” Kerry told Perino.

“We knew that Assad had kept some, and we tried to go to the Security Council, and, unfortunately, Russia played games and we didn’t get there,” he explained.

Kerry further said he agreed with President Donald Trump’s decision to strike Syrian government military installations after Assad reportedly used chemical weapons in April of both 2017 and 2018 to attack his own people.

“The evil and despicable attack left mothers and fathers, infants and children thrashing in pain and gasping for air. These are not the actions of a man. They are crimes of a monster instead,” Trump said in his address to the nation on the evening of the strikes.

“I agreed with President Trump’s use of force. I thought it was the appropriate thing to do,” Kerry said, adding more needs to be done diplomatically since there is not a “military solution to the opposition” in the country.
